Evaluating the design of a stormwater quality improvement device with CFD

Stormwater is surface water runoff from urban areas discharging into receiving waterways. Litter and pollutants collected along the path of urban runoff can have a devastating effect on the environment. In order to improve the quality of runoff discharging into urban waterways, stormwater quality improvement devices (SQID) were developed to efficiently trap urban waste of varying sizes such as sludge, silt, sediments and solids.
Gross pollutant traps (GPTs) are a class of SQIDs that separate litter or debris (dimensionally greater than 5 mm) from stormwater, and these are usually installed downstream of the stormwater intake or the network line to prevent gross pollutants such as litter entering into receiving waterways. Proprietary developed SQIDs often lack rigorous design assessment.
In this research, design assessment of a GPT is undertaken via computational fluid dynamics (CFD) simulation and experiments on a LitterBank 50% scale model. The purpose of this research is to develop a design tool based on CFD by validating the numerical results with experiments.
